Objective To assess the relationship between gastric carcinoma perfusion imaging parameters with the multislice spi-ral CT (MSCT)and the tumor angiogenesis(MVD,VEGF).Methods (1)33 patients with gastric cancer were carried on perfusion CT scanning in the suspected lesions,and compared with operation and histological result.MSCT perfusion parameters tumor,such as local blood flow (BF),blood volume (BV),mean transit time of contrast agent (MTT),permeability surface (PS),were recor-ded,and compared with clinical pathological data.(2)27 patients of 33 cases which CT perfusion plane matching with operation pa-thology specimens performed with tumor microvessel density (MVD),vascular endothelial growth factor (VEGF)monoclonal anti-body immunohistochemical examination of MVD,the most intensive areas of high power (×200 HP)field counted,and VEGF stai-ning positive judged.Results Achievement ratio of gastric carcinoma MSCT perfusion imaging was 84.85% (28/33).The average value of BF,BV,MTT and PS were 63.658 ± 18.305,7.5 1 1 ± 2.427,1 1.952 ± 4.325 and 31.81 7 ± 13.533,respectively,and MVD was 37.7 ± 11.1/200 HP (range:13-60).VEGF was positive in 16 cases,negative in 11 cases.Gastric carcinoma undifferentiated group perfusion parameter PS value (35.1 5 ± 12.74 )and MVD (40.53 ± 10.66 )were higher than the differentiation group (23.90 ± 12.71 and 31.13 ± 9.82 )(P < 0.05 ),but BF,BV,MTT not statistically significant;Differences of CT perfusion parameters and MVD were not significant statistically between invasive serosa and noninvasive ;PS value (36.65± 12.80)of lymph node metastasis was greater than without metastasis(22.70 ± 1 1.1 5 )(P <0.01 ),the other was no significant difference;TNM staging Ⅲ,Ⅳ phase group of BF value (69.56 ± 1 6.49),PS value (34.90 ± 12.80)and MVD value (40.74 ± 10.53)were higher than Ⅰ,Ⅱ Group (49.63 ± 1 5.04),(24.50 ± 13.13)and (30.63 ± 9.61)(P <0.01).Spearman correla-tion analysis in confidence (two tails)of 0.01 was statistically significant between MVD in tumor tissues and gastric cancer MSCT perfusion parameters of BF (r=0.404)and MTT (r=0.371),whereas BV and PS were no significance.The regression equation of MVD with BF and MTT:MVD =1 6.602+0.1 50XBF +0.967XMTT,model checking of F values was 6.62,P =0.003.Conclusion The gastric carcinoma multi-slice CT perfusion imaging parameters BF,MTT and MVD,VEGF(+)was positive correlation, MSCT perfusion imaging parameters reflects tumor VEGF positive expression of gastric carcinoma.

Objective To compare the effect of fluoroscopic triggering method and empirical delay method on image quality in the liver Gd-EOB-DTPA dynamic enhanced MRI,and to investigate the value of fluoroscopic triggering method in Gd-EOB-DTPA dynamic enhanced MRI.Methods The patients underwent Gd-EOB-DTPA dynamic enhanced MRI were randomly divided into two groups according to the starting modes in the artery phase.Group A used fluoroscopic triggering method and group B used empirical delay method.Eliminating the images with severe respiratory motion artifacts,the quality of the remaining images in 78 cases of group A and 85 cases of group B were assessed in scores (excellent=5 scores;good=4 scores).Data was statistically analyzed with Mann-whitney tests,and P<0.05 was considered statistically significant.Results The excellent rate of the images in group A was 96.15% (75/78).The excellent rate of the images in group B was 67.06% (57/85).There were significant differences between the two groups in the excellent rate (χ2=27.889, P<0.001)and the image quality scores (Z=-4.747,P<0.001).Conclusion For the liver Gd-EOB-DTPA dynamic enhanced MRI, fluoroscopic triggering method is more likely to get better image quality and higher success rate in artery phase than empirical delay method,which indicates that fluoroscopic triggering method have obviously advantages in clinical applications.

Objective: To study the expression of PDCD5 mRNA and its significance in esophageal cancer in Xinjiang Kazakh and Han nationality. Methods: RT-PCR was used to detect the mRNA of PDCD5 in 40 cases of esophageal cancer (18 cases of Kazakh, 22 cases of Han). Results: The positive rate of PDCD5 mRNA expression in 40 samples of esopha-geal cancer tissue, adjacent tissue, and normal tissue was 80.0% (32/40), 80.0% (32/40) and 87.5% (35/40), respectively, with no significant difference (P>0.05). The Ods of cancer tissues, adjacent tissues, and normal tissues were 0.7644± 0.1444, 0.9341 ±0.1631 and 1.8703±0.4767, respectively. The expression of PDCD5 was significantly increased in cancer tissues compared with that in normal tissues (P<0.05). The expression level of PDCD5 mRNA was not significantly correlat-ed with the degree of differentiation and lymph node metastasis. Conclusion: No significant difference was found in PDCD5 mRNA expression in esophageal cancer between Xinjiang kazakh and Han nationality (P>0.05). The expression of PDCD5 is not correlated with the degree of differentiation, depth of invasion or lymph node metastasis. Detection of PDCD5 mRNA expression in esophageal cancer tissues may provide valuable information for patient prognosis.

Objective To analyze the change of schistosomiasis endemic situation in Hubei Province, 2008. Methods The data of schistosomiasis control in the whole province, surveillance sites and standard examinations were collected and analyzed. Results Among all the 63 endemic counties (cities, districts), 21 reached the criteria of transmission interruption, 19 reached the criteria of transmission control, and 23 reached the criteria of infection control in 2008. Villages of Category Three, Category Four and Category Five accounted for 52.10% , 27.80% and 20.09% of all the endemic villages in the whole province, respectively. The infection rates of population and cattle were 1. 70% and 2. 20% , which decreased by 27. 04% and 34. 33% when comparing to those in 2007. The snail area was 77 363 hm~2, with a reduction of 315.70 hm~2 comparing to 2007. In the 74 provincial surveillance sites, the infection rate of population and cattle were 1. 32% and 1. 85% , respectively, with reduction rates of 32.99% and 68.38% comparing to 2007. The snail area was 2 833.98 hm~2 and the area with infected snails was 215.35 hm~2, the densities of living and infected snails were 0. 37 snails/0.1 m~2 and 0.000 3 snails/0. 1 m~2, respectively, and the infection rate of snails was 0.08%. Comparing to 2007, the snail area, densities of living and infected snails and the infection rate of snails decreased by 3.81 % , 21.28% , 40.00% and 27. 30% , respectively, while the area with infected snails increased by 4.52%. The results of standard examination suggested that all the 15 uncontrolled counties ( cities, districts) reached the criteria of infection control. Conclusions Though the endemic situation of schistosomiasis in Hubei Province has been controlled effectively, the endemic condition is still severe. Therefore, the comprehensive measures with an emphasis on infectious source control should be strengthened to consolidate the control result.

Objective To analyze the Oncomelania hupensis snail situation in schistosomiasis surveillance sites in Hubei Province from 2009 to 2014. Methods From 2009 to 2014,207 schistosomiasis endemic villages from 13 cities were selected as the surveillance sites in Hubei Province,where the surveillance of snail situation was performed,and the data about the in?dexes of snail situation during the 6 years were collected and analyzed statistically. Results From 2009 to 2014,totally 80 963.47 hm2 of snail areas were investigated,and 45 309.77 hm2 of area with snails as well as 364.93 hm2 of area with infected snails were found out,and 1 646 125 snails were captured. In the 207 surveillance sites,the density of living snails was reduced from 0.493 3 snail/0.1 m2 in 2009 to 0.339 3 snail/0.1 m2 in 2014,with a decline rate of 31.22%;the density of infected snails was reduced from 0.000 7 snail/0.1 m2 in 2009 to 0 in 2014;the infection rate of snails was reduced from 0.14%in 2009 to 0 in 2014. The infection rates of snails in the third?rank villages,endemic areas in inner embankment,ditch environment and weed environment were relatively higher. Conclusions The snail situation of Hubei Province has been declined steadily. However, the environment of snail breeding has not been changed completely. In order to consolidate the control achievements further ,the measures including mollusciciding and snail control projects should be strengthened.

Objective: To investigate the factors influencing the development of gastric cancer in Chinese populations, so as provide insights into creating a model for predicting gastric cancer incidence among Chinese populations. Methods: The case-control and cohort studies pertaining to factors affecting the development of gastric cancer were retrieved in electronic Chinese and English databases, including CNKI, Wanfang Data, VIP, PubMed, Web of Science and Embase from their inception until September 30, 2021. A meta-analysis was performed using R package version 4.1.0. Sensitivity analysis was performed using the “leave-one-out” evaluation procedure, and the publication bias was evaluated using the Egger regression test and the trim-and-fill procedure. Results: A total of 5 301 publications were screened and 116 eligible studies were included in the final analysis, including 103 case-control studies and 13 cohort studies, which covered approximately 3.23 million study subjects. A total of 45 factors affecting the development of gastric cancer were collected, and there were less than 4 publications reporting 7 factors, which were only qualitatively described. There were 38 factors included in the final meta-analysis. A total of 21 factors were identified as risk factors of gastric cancer, including a history of gastrointestinal diseases (pooled OR=4.85, 95%CI: 3.74-6.29), H. pylori infection (pooled OR=3.18, 95%CI: 2.35-4.32), binge eating and drinking (pooled OR=2.88, 95%CI: 2.09-3.97) and a family history of tumors (pooled OR=2.78, 95%CI: 2.17-3.56), and 10 factors as protective factors, including vegetable intake (pooled OR=0.48, 95%CI: 0.38-0.61), tea consumption (pooled OR=0.55, 95%CI: 0.47-0.64), administration of aspirin (pooled OR=0.53, 95%CI: 0.31-0.92) and administration of statins (pooled OR=0.59, 95%CI: 0.44-0.80). Sensitivity analyses of eating moldy food frequently, white meat intake, favoring spicy food and administration of sulfonylureas were not robust. Following correction with the trim-and-fill procedure, there was still a publication bias pertaining to high income, diabetes, administration of stains, alcohol consumption, tea consumption and white meat intake. Conclusions The development of gastric cancer is associated with a medical history of gastrointestinal disease, H. pylori infection, family history of tumors and poor dietary habits. Risk and protective factors of gastric cancer are recommended to be included in models used to predict gastric cancer incidence among Chinese populations.
